Avoid Conflicts

For a good carrier this thing should be must. whenever you are not agree with your senior person do not be in hurry to refuse.
Each person have their own ego we can not ignore it at all.so you can just give your doubts to him/her and ask opinion rather giving suggestion.
(personally i learn this tactics by my own personal experience ).
Keeping cool head with a hot ideas are the key to success in any industry.
always keep your logic moving but make your head still.
